  • Notes

  • A hi-fi stereo integrated amplifier housed in a black metal case with infrared remote control with continuous power output of 2 x 60 watts into 8 ohms (2 x 70 watts DIN into 8 ohms). With Pioneer's Super Linear Circuit and Clean Ground System. Anti-resonance and vibration design with honeycomb chassis and heat sink. With Bass and Treble tone controls (with Active Tone Control), rotary switch for Speakers (A, B, A+B), switches for Direct, Subsonic filter and Muting and a jack for headphones. On the rear panel, RCA phono sockets for input PHONO, LINE, CD, for input/output DAT/TAPE1, TAPE2, ADAPTOR (I/O connected by removable links) and terminals for 2 pairs of loudspeakers.
